We mentioned Representable a few weeks ago as well, so its worth mentioning some updates. Changes include better handling of nil and false values, and the ability to represent a hash as a series of attributes on an xml element. Some of the changes are potentially api-breaking though, so upgrade with care!

Mat Schaffer wrote in to tell us about his new gem knife-solo. This gem adds a few new commands to knife for working with chef-solo, including installing chef-solo on 8 different remote operating systems, installing and running your recipes on those systems, and cleaning up afterward.
